The evening being with the Obstreperous Doves, a project by Bill Noertker that brought together Nava Dunkelman, Christina Stanley, Karl Evangelista, and Dave Mihaly in an exploration of assertive and complex improvisation.

Besides giving us a chance to use the word “obstreperous” – and it is indeed a fine word – the ensemble allowed the talents of all five artists to blend while still letting them each have a voice. Christina Stanley provided noisy and harmonic violin sounds as well as her voice, including a strange but amusing story layered on top of pieces. Nava Dunkelman offered up a wealth of percussive sounds that also sang at times. Karl Evangelista was in usual form with his intense and intricate guitar playing. The group lived up to its name with lots of noisy percussive sections, but also moments of more harmonic jazz phrases, and quiet instances as well.

The Obstreperous Doves were followed by the Bob Marsh’s ensemble the Emergency String (X)tet. They premiered a Terrascore by Marsh composed for his 70th birthday.

A terrascore is “a musical geobiographic representation of an individual.” In this case it focused on locations significant to Marsh’s artistic life: his home town of Detroit, Chicago, Berkeley and San Francisco. The ensemble improvised with Marsh conducting from a score based on geographical information from these places, along with field recordings that he made. I’m pretty sure I recognized the one that represented the area around the Luggage Store Gallery in San Francisco. The other members of the ensemble included Mia Bella D’Augelli, Jeff Hobbs,Christina Stanley (pulling double-duty on this night), David Michalak, Doug Carroll, and Kanoko Nishi-Smith.

The final performance was a trio that brought together vocalist Jill Burton with Tim Perkis on electronics and Doug Carroll (also pulling double-duty) on cello. This was a first-time collaboration by the three of them. The result very captivating performance. It started with a very mysterious and haunting solo by Jill Burton, who then demonstrated the range of her extended vocal techniques blending with Perkis’ liquidy electronic sounds and Carroll’s scratchy percussive cello. It was also a theatrical performance, with expressive gestures and movement by Burton coupled with Carroll’s cello antics, sometimes turning the instrument backwards or upside down. But all along with a sonically beautiful and varied experience, that contained the right amount of silence amidst the energy of the sounds.

It was a very strong finale to this year’s summit, and it was interesting to compare and contrast the book ends of the Jill Burton trio with Pitta of the Mind from the opening. It was probably among the best years overall since I started attending this event in 2008; and I look forward to what comes next year.
